Symptom 2

When a trouble with the power supply which drives the IGBT at the VCU side occurs, the PCU detects a trouble (F15V) with the GDIC function and, at the same time when outputting a failure information (F15V) to the high-voltage microcomputer, blocks a gate signal. If an F15V signal detects a trouble for the specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
